Stains & Dyes

Ponceau S: Ponceau S is the sodium salt of a diazo dye. It is used to make a stain for rapid reversible staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes.

For use in slide preparations of specimens for the purpose of identifying fungal elements.

An aqueous solution of potassium permanganate.

Propidium iodide (PI) is a red-fluorescent cell viability dye which is excluded from live cells as it is impermeable to the cell membrane. The dye intercalates DNA and RNA of the dead cells to give red fluorescent signal as it can penetrate dead or
